Django Sign Up and login with confirmation Email

Django by default provides an authentication system configuration. User objects are the core of the authentication system.today we will implement Django’s authentication system.

Modules required :

django : django install

crispy_forms :

pip install --upgrade django-crispy-forms

Basic setup :

Start a project by the following command –

 django-admin startproject project

Change directory too project –

 cd project

Start the server- Start the server by typing following command in terminal –

 python manage.py runserver

To check whether the server is running or not go to a web browser and enter http://127.0.0.1:8000/ as URL.

Now stop the server by pressing

ctrl-c

Let’s create an app now called the “user”.

python manage.py startapp user

Goto user/ folder by doing: cd user and create a folder templates with files index.html, login.html, Email.html, register.html files.

Open the project folder using a text editor. The directory structure should look like this :

Now add the “user” app and “crispty_form” in your todo_site in settings.py,
and add

CRISPY_TEMPLATE_PACK = 'bootstrap3'

at last of settings.py

configure email settings in setting.py:

place your email and password here.

Edit urls.py file in project :

from django.contrib import admin 
from django.urls import path, include 
from user import views as user_view 
from django.contrib.auth import views as auth 
  
urlpatterns = [ 
  
    path('admin/', admin.site.urls), 
  
    ##### user related path##########################  
    path('', include('user.urls')), 
    path('login/', user_view.Login, name ='login'), 
    path('logout/', auth.LogoutView.as_view(template_name ='user / index.html'), name ='logout'), 
    path('register/', user_view.register, name ='register'), 
  
] 

Edit urls.py in user :

from django.urls import path, include 
from django.conf import settings 
from . import views 
from django.conf.urls.static import static 
  
urlpatterns = [ 
         path('', views.index, name ='index'), 
] 

Edit views.py in user :

from django.shortcuts import render, redirect 
from django.contrib import messages 
from django.contrib.auth import authenticate, login 
from django.contrib.auth.decorators import login_required 
from django.contrib.auth.forms import AuthenticationForm 
from .forms import UserRegisterForm 
from django.core.mail import send_mail 
from django.core.mail import EmailMultiAlternatives 
from django.template.loader import get_template 
from django.template import Context 
   
   
#################### index#######################################  
def index(request): 
    return render(request, 'user / index.html', {'title':'index'}) 
   
########### register here #####################################  
def register(request): 
    if request.method == 'POST': 
        form = UserRegisterForm(request.POST) 
        if form.is_valid(): 
            form.save() 
            username = form.cleaned_data.get('username') 
            email = form.cleaned_data.get('email') 
            ######################### mail system ####################################  
            htmly = get_template('user / Email.html') 
            d = { 'username': username } 
            subject, from_email, to = 'welcome', 'your_email@gmail.com', email 
            html_content = htmly.render(d) 
            msg = EmailMultiAlternatives(subject, html_content, from_email, [to]) 
            msg.attach_alternative(html_content, "text / html") 
            msg.send() 
            ##################################################################  
            messages.success(request, f'Your account has been created ! You are now able to log in') 
            return redirect('login') 
    else: 
        form = UserRegisterForm() 
    return render(request, 'user / register.html', {'form': form, 'title':'reqister here'}) 
   
################ login forms###################################################  
def Login(request): 
    if request.method == 'POST': 
   
        # AuthenticationForm_can_also_be_used__ 
   
        username = request.POST['username'] 
        password = request.POST['password'] 
        user = authenticate(request, username = username, password = password) 
        if user is not None: 
            form = login(request, user) 
            messages.success(request, f' wecome {username} !!') 
            return redirect('index') 
        else: 
            messages.info(request, f'account done not exit plz sign in') 
    form = AuthenticationForm() 
    return render(request, 'user / login.html', {'form':form, 'title':'log in'}) 

Configure your email here.

Now create a forms.py in user :

from django import forms 
from django.contrib.auth.models import User 
from django.contrib.auth.forms import UserCreationForm 
  
  
  
class UserRegisterForm(UserCreationForm): 
    email = forms.EmailField() 
    phone_no = forms.CharField(max_length = 20) 
    first_name = forms.CharField(max_length = 20) 
    last_name = forms.CharField(max_length = 20) 
    class Meta: 
        model = User 
        fields = ['username', 'email', 'phone_no', 'password1', 'password2'] 

Navigate to templates/user/ and edit files :

Make migrations and migrate it.

python manage.py makemigrations
python manage.py migrate

Now you can run the server to see your app.

python manage.py runserver
